This mission follows an unorthodox structure in that Commander Shepard goes solo as he navigates the inside of a geth server.

Armed with a special weapon of some sort, you are to blast away any corrupted data blocks (indicated by a fiery orange glow) whenever you encounter them. The goal is to simply follow the blue tiles as they are assembled when you walk toward them, and purge the Reaper infection. Make your way to the blue beams of light called access points to be taken to other infected parts.

Reaper Code Fragments - for Citadel: Reaper Code Fragments - Found in the second server area (i.e. After exiting the "Access Point"). To find these wait for Legion to mention someting about "Data clusters containing infected code." When Legion mentions this check along the pathway to the left. If you miss the fragments, they will become available at your Spectre Terminal on the Citadel.

Get rid of the infections on data clusters by chiseling away at any bright orange spots on the large clusters. You'll know you've mined the data from the clusters when holograms of quarian and geth appear.

Eventually, you'll run into indestructible Reaper tendrils that regenerate just as quickly as you destroy them. Geth VI (or Legion) advises that you seek out and destroy weaker points to delay the regeneration. These weak-spots are denoted by sections located elsewhere that are smaller in circumference (and still glow orange). Destroy these first to be able to sear off the thicker parts.

Mine a few more data clusters and return to the last access point to leave.
